Subject Client library mystery
Author willy_metra

i would like to ask someone kind for a help, please.
(i'm sorry for my, may-be, newbie question)

I tried to rewrite my db app from IBX&IB6 to famous IBO&FB1.5.
I think IBO works with with both db engines, InterBase and FireBird,

1. Do i have to specify in IBO what engine i'm using, please?
If so how to do that, please?

2. I have to keep access to both (IB, FB) db engines. Someone kind,
in this group, helped me with deploying client library. Told me, that
there's preferred client (gds32.dll) library in app path, instead of
the one placed in system directory. So i have one IB library in system
and FireBird one in app path, and here comes the mystery:

Everything goes fine, except i have installed IB7 engine on the
machine, then firebird library won't run from app path and even from
system path.

Thank you very much for any response, Jan Byvaly.
